“How can there be such a wide chasm between Gedolim, with some showing much veneration for the Rebbe, while others said that Chabad mikvaos are posul, our wine is assur, you shouldn’t be meshadech with us, and our children are Bnei Niddah.
“And then you wonder why we still can’t respect Gedolim who said those things”
Well, according to The Ba’al haTanya in the Igros — Yes.
